Answer:
3x + 3y
Step-by-step explanation:
X + 2X = 3X
Y + 2Y = 3Y
In this expression, we can combine the like terms to simplify it.
Explanation:To simplify the expression x + 2x + y + 2y, we can combine the like terms. Like terms are terms that have the same variables raised to the same power. In this case, the terms 2x and x are like terms because they both have the variable x raised to the power of 1. Similarly, the terms 2y and y are like terms because they both have the variable y raised to the power of 1.
So, when we combine the like terms, the expression becomes 3x + 3y.

PLEASE HELP, WILL MARK BRAINLIEST!! The diagram shows the dimensions of a deck. A student finds the area by adding 16 ft2 + 48 ft2. Is the student correct? Explain your reasoning.
Answer:
The student is wrong, the total area = 16 ft² + 20 ft²
Step-by-step explanation:
The figure can be consists of :
1) A square of side length of 4 ft
2) A trapezoid of height (8-4 = 4 ft) and the bases length is (6 and 4 ft)
So,
The area of the square = 4 * 4 = 16 ft²
The area of the trapezoid = 0.5 (6+4) * 4 = 5 * 4 = 20 ft²
So ,the total area = 16 + 20 = 36 ft²
So,
The student is distracted.
he have found the area of total rectangle of length of 8 ft and width of 6 ft instead of the area of the trapezoid.
So, the student is wrong

9. Rama is using a hand glider to fly directly from the top of one cliff onto another cliff below. The glider is guided by a cable. The cliffs are 740 feet apart and the first cliff is 280 feet taller than the second cliff. How long is the cable between the cliffs?
Answer:
791.2 ft
Step-by-step explanation:
The cable is inclined and this acts as the hypotenuse. Since the other two sides are given.
[tex]H=\sqrt {x^{2}+y^{2}}[/tex]
where x and y represent the distance between two cliffs apart and difference in heights. Substituting 740 for x and 280 for y then
[tex]H=\sqrt {740^{2}+280^{2}}=791.20161779409930627669981858168023442712 ft\approx 791.2 ft[/tex]
Answer:
791.2 ft to the nearest tenth.
Step-by-step explanation:
From the diagram,we assume :
AD to be the height of the first cliff
BC to be the height of the second cliff
DC to be the length of the cable between the top of the two cliff.
AD=740 ft.
DE= 280 ft.
Using Pythagorean Theorem, we obtain.;
[tex] {DE}^{2}+ {CE}^{2} = {DC}^{2} [/tex]
By substitution we obtain
[tex] {280}^{2} + {740}^{2} = [/tex]
[tex] \implies78400 + 547600 = {DC}^{2} [/tex]
[tex]\implies626000= {DC}^{2} [/tex]
Taking positive square root.
[tex]\implies DC = \sqrt{626000} [/tex]
[tex] \implies DC =791.202 ft[/tex]

Answer:
8.8
Step-by-step explanation:
if you use the sin, cos, and tan method. 20 is the h, x is the a and the blank side is the o. if you take way the side without the o you have the a and h which means you have cosine. If you did the equation as cos64=x/20 Then multiply both sides by 20 to get the X by it so you will have 20 COS 64 and once you want a play that together you have 8.8 equals X.

and trace it on the cumulative frequency curve.
From the graph, that total frequency is 100.

Gigi spent 12% of her birthday money on a new pair of sunglasses. What fraction of her birthday money did she spend in the new sunglasses
Answer:
3/25
Step-by-step explanation:
You know that percent is out of 100, so that's 12/100
Then simplify the fraction to 6/50 then 3/25
Final answer:
Gigi spent 12% of her birthday money on sunglasses, which is equivalent to 3/25 of her birthday money when converted and simplified from a percentage to a fraction.
Explanation:
Gigi spent 12% of her birthday money on a new pair of sunglasses. To find out what fraction of her birthday money this represents, we convert the percentage to a fraction. Percent means 'per hundred,' so 12% can be written as 12 per 100 or, more simply, 12/100. However, this fraction can be simplified further. Both the numerator (12) and the denominator (100) can be divided by their greatest common divisor, which is 4. Dividing both by 4, we get 3/25. Therefore, Gigi spent 3/25 of her birthday money on the new sunglasses.

10×4^14
10×4^15
4×10^15
4×10^14
The frequency of red light is 4 x 10¹⁴ Hz. The correct answer is option D.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
The given that when the frequency of an electromagnetic wave is 400,000,000,000,000 Hz, it results in red light.
The choices given are in scientific notation form, where the coefficient is multiplied by 10 raised to a certain power of 10.
To convert 400,000,000,000,000 Hz into scientific notation, we need to move the decimal point 14 places to the left to obtain a coefficient between 1 and 10.
This gives us 4.0 as the coefficient, and since we moved the decimal point 14 places to the left, the power of 10 is -14.
Therefore, the frequency of red light is 4 x 10¹⁴ Hz.

Four CDs and 4 DVDs cost $164. The cost of the 4 CDs is half the cost of the
4 DVDs. What is the cost of each CD?
Answer:
$13.67
Step-by-step explanation:
Let's say that CD= c and DVDs= d. Four CDs and 4 DVDs cost $164, so the equation will be:
i. 4c + 4d= 164
The cost of the 4 CDs is half the cost of the 4 DVDs, to put into an equation it will be:
ii. 4c= 0.5(4d)
4c= 2d
d= 2c
Then we can substitute the second equation (ii) into the first equation (i). The calculation will be:
4c + 4d= 164
4c + 4(2c)= 164
4c+ 8c= 164
12c= 164
c=13.67
The cost for each CD is $13.67

Which answer is correct?
Well, since the graph starts at (0,50), making our y-intercept 50, we can knock off D as an option.
The next step is to find the slope. To do this, find two points and subtract the y values over the x values. (Just make sure that whichever y value you start with - start with the same x value).
So we have >>> (50, 200) and (0,50) from earlier.
200 - 50 / 50 - 0 = 150/50 or 3/1, or 3.
This makes the correct answer A since the equation is represented as y = mx + b, where m is the slope and m has a value of 3.

To find the bearing of point X from point Z, we can use the given bearings of points X, Y, and Z. Here's how:
Start with the bearing of point Z from point X, which is 110°.Add the bearing of point Z from point Y, which is 125°.Subtract the bearing of point Y from point X, which is 70°.The result is the bearing of point X from point Z. So, the bearing of point X from point Z is 165°.
Line v has a slope of -5/2
Line w is parallel to line v. What is the slope of line w?
Simplify your answer and write it as a proper fraction, improper fraction, or integer,
Answer:
-5/2
Step-by-step explanation:
Since they are both parallel they have the same rate of change. this means they have the same slope
Final answer:
Since line w is parallel to line v, which has a slope of -5/2, the slope of line w is also -5/2.
Explanation:
When two lines are parallel, they have the same slope. In this case, the slope of line w will be the same as the slope of line v.
Therefore, the slope of line w is -5/2.
The question asks about the slope of two parallel lines. By definition, parallel lines have the same slope. Given that line v has a slope of -5/2, and line w is parallel to line v, the slope of line w must also be -5/2. Therefore, line w, being parallel to line v, has a slope of -5/2.

3x+2y=8 is this function a quadratic?
Step-by-step explanation:
Let's select values for X, and find the corresponding Y values:
X = -3, Y = 8.5
X = -2, Y = 7
X = -1, Y = 5.5
X = 0, Y = 4
X = 1, Y = 2.5
X = 2, Y = 1
X = 3, Y = -0.5
So our coordinates are:
(-3, 8.5) ; (-2, 7) ; (-1, 5.5) ; (0, 4) ; (1, 2.5) ; (2, 1) and (3, 0.5)
Graph these on a chart to visualize:

We can see that this is a decreasing linear function, not quadratic. Quadratic functions create a symmetrical curve, which this is not.

h(x)=square root of x-10
what is the domain of h?
The domain of the function h(x) = √(x-10) is all real numbers x that are greater than or equal to 10, because we cannot take the square root of a negative number under the real number system.
Explanation:In mathematics, the domain of a function is the set of all the possible input values (usually denoted as x) that would lead to a real and defined output. As for the function h(x)=√(x-10), we have a square root operation involved. We know that under the real number system, we cannot take the square root of a negative number.
Hence, for the function h(x)=√(x-10) to be real and defined, (x-10) must be greater than or equal to 0. That is, x-10 ≥ 0. Solving for x, we get x ≥ 10.
Therefore, the domain of the function h(x) = √(x-10) is x≥10. That is, h(x) is defined for all real numbers x that are greater than or equal to 10.
